This is the second of our very easy Eleven Plus maths quizzes on multiplication and division. In it you’ll learn some techniques and strategies that will make your calculations even easier to do. Try all the quizzes in our very easy section before moving up a level.

One thing which will help you no end when dividing or multiplying numbers, is knowing all your times tables off by heart. That way you’ll avoid having to rely on calculators or pencils and paper. I mean, you wouldn’t want to get either of those out if you were in a shop trying to work out how much something will cost you to buy, would you?

The questions here are quite simple. Nevertheless, you’d be wise to read each of them carefully before selecting your answer. Get used to doing that now and it’ll be second nature when you take your exams.

1.

What is the correct answer to the given calculation?

999 × 11

999 × 11

1,089

10,890

10,989

110,889

2.

What is the correct answer to the given calculation?

36 x 20

36 x 20

576

648

720

900

To multiply by 20, first multiply by 2 then by 10:

36 x 2 = 72, then 72 x 10 = 720

36 x 2 = 72, then 72 x 10 = 720

3.

What is the correct answer to the given calculation?

250 quintupled

250 quintupled

500

750

1,000

1,250

'Quintupled' means multiplied by five. A quick way to work this problem out is to first multiply by 10, and then divide by 2:

250 x 10 = 2,500, then 2,500 ÷ 2 = 1,250

250 x 10 = 2,500, then 2,500 ÷ 2 = 1,250

4.

What is the correct answer to the given calculation?

750 ÷ 5

750 ÷ 5

150

75

300

250

To swiftly divide by 5, first divide by 10 then double your answer:

750 ÷ 10 = 75, then 75 x 2 = 150

750 ÷ 10 = 75, then 75 x 2 = 150

5.

What is the correct answer to the given calculation?

1,000,000 (1 million) ÷ 2,000

1,000,000 (1 million) ÷ 2,000

50

100

500

1,000

To quickly divide by 2,000, first divide by 1,000, then divide your answer by 2:

1,000,000 ÷ 1,000 = 1,000, then 1,000 ÷ 2 = 500

1,000,000 ÷ 1,000 = 1,000, then 1,000 ÷ 2 = 500

6.

What is the correct answer to the given calculation?

1.8 x 400

1.8 x 400

720

7,200

72

7.2

To multiply by 400, first multiply by four, then by 100:

1.8 x 4 = 7.2, then 7.2 x 100 = 720

1.8 x 4 = 7.2, then 7.2 x 100 = 720

7.

What is the correct answer to the given calculation?

174 ÷ 100

174 ÷ 100

0.174

1.74

17.4

0.0174

To divide by 100, simply move the decimal point two places to the left. Remember that, in whole numbers, the decimal point comes after (i.e. 174 is the same a s 174.00000)

8.

What is the correct answer to the given calculation?

16 trebled

16 trebled

4

8

32

48

'Trebled' means multiplied by 3

9.

What is the correct answer to the given calculation?

17 quadrupled

17 quadrupled

28

34

51

68

'Quadrupled' means multiplied by 4

10.

What is the correct answer to the given calculation?

28 × 99

28 × 99

252

2,772

532

3,052

A quick way to multiply by 99 is to first multiply by 100, then subtract the original number:

28 x 100 = 2,800, then 2,800 - 28 = 2,772

28 x 100 = 2,800, then 2,800 - 28 = 2,772

11 x 1,000 = 11,000. Then 11,000 - 11 = 10,989.

To quickly multiply by 11, first times by 10, then add the original number:

999 x 10 = 9,990. Then 9,990 + 999 = 10,989
